Lee Branch is a tributary of Alexander Creek, which is described
in a
November '03 post, and drains the section of the Brevard Belt
immediately
south of Station Cove. The tall trees are concentrated in four
topographically complex coves south of Lee Branch. The
southernmost of
the coves faces east with two small branches running through the
area.
The land in between the branches consists of a bench that leads
into a low
ridge below and above gives rise to a slope inclined at over 30
degrees.
Tuliptree and pignut hickory form most of the canopy in that
area with
some northern red oak and a little siverbell and white ash. Oaks
take on
a greater role around the edges of the cove with white, black,
or chestnut
dominating depending on the aspect. Some canopy dominants were
probably
removed by past logging, but trees over 150 years old remain
scattered
throughout the cove. Yellow buckeye forms a midstory along the
streams
and rhododendron and dog-hobble occur as scattered clumps in the
understory. Bloodroot and rue anemone are the most common
herbaceous
plants with some violets and mayapple also present.
The next cove to the has a much spacer herbaceous layer,
probably due to
drier conditions. The ridges bordering the cove rise less than
100' above
the drainage, and second-growth oaks dominate with a few
tuliptrees along
in the middle. The cove adjacent on the north side is notably
asymmetrical, and appears to have a very different disturbance
history.
One side of the cove consists of a broad, gentle, southeast
facing slope
with a poorly defined edge while a short, steep, north-facing
slope forms
the other side of the cove. The more gentle side of the cove
shows minor
terracing, and the area was clearly farmed in the past.
Tuliptree
dominates close to the drainage with some northern red oak, but
gradually
becomes less common on the gentler side of the drainage mixing
with white
and black oaks. On the drainage small yellow buckeyes shade
mayapples
while redbuds bloom over pennywort in the farmed area.
The northernmost of the four coves is more of an open, north
aspect slope
with somewhat of a stair-stepped profile. A small ridge and an
unnamed
tributary of Lee Branch with a cascade border opposite sides of
the area,
and Lee Branch itself flows at the base of the slope. A mix of
deciduous
species grow on the lower slopes with the component of oaks
increasing
with elevation. Patches of rhododendron and dog-hobble also
occur on the
lower slope with some hemlock in the understory. The upper slope
is more
open, and rue anemone is the most common herbaceous species.

The pignut hickory listed above is the second tallest currently
known in
the state and the third tallest confirmed by ENTS. Similarly,
the two
tallest black oaks listed above are the two tallest known in the
state,
and the taller of the two is the second tallest confirmed! The
taller of
the two is also fairly young and has potential for further
growth. The
tallest of the northern red oaks is the second tallest now
located. The
tree would be easy to measure if not for the dense cluster of
tuliptrees
surrounding the tree. Consequently, I'm not sure if the two
measurements
I took of the tree from approximately 90 degrees apart are of
the same
top. The listed height for the tree is the average of the 149.2'
and
150.8' measurements. The tree is well under 100 years old, and
has plenty
of competition to force continued height growth; the the
substantial lean
and advanced basal root may lead to mechanical failure before
the tree
grows much taller. The 128.2' scarlet oak is also note worthy as
the
second tallest of the species known in the state. The site is
also the
third known in the state to support a tuliptree over 160'.
However, an enormous pignut hickory growing on the edge of the
bench in
the southernmost cove is by far the most impressive tree in the
area. I
measured the tree last year at 154.7'; but that was with a poor
shot at
the base, and I knew the tree was taller. That measurement
combined with
shooting vertically with the rangefinder made me think the tree
would top
160', but not exceed the Chum Cove pignut. Consequently, I spent
two
hours one day in March measuring the tree. The lower trunk
tapers from
13'6" at grade on the uphill side to 11'5" at bh, and
remains just over
11' at six feet above mid-slope! Above that height, the tree
extends
another 74.0' to where the trunk forks and spreads into a crown
spanning
63'. I took a total of five measurements to four different twigs
from
three different positions spanning about 120 degrees. The one
twig
measured from two positions yielded 167.8' and 168.2'! The other
tops
measured 167.1', 168.2', and 168.53'! Using 168.2' for the
height, the
tree has 321 big tree points!
That tree brings the Rucker Index for the Alexander Creek
watershed to
140.14', with only the black locust not in the Lee Branch
watershed. A
total of 16 species have now been measured over 100' at the
site. The
slope by Lee Branch, an area of less than 20 acres, is also
remarkable for
supporting five different species of oaks over 120' in such a
small area!
Plenty of justification also exists for calling Alexander Creek
the land
of the pignut hickories since two of them exceed 150' tall and
five are
over 11' cbh!

>> Is this a national champion?<<
One of the
Georgia barrier islands has a pignut listed at 16'8" cbh
with a
huge crown; however, the Lee Branch tree has only 15 fewer
points and
probably has much greater volume. The Chum Cove tree may still
have the
greatest volume due to the higher point of branching and the
remarkably
slow taper of the upper trunk, but the two should still be very
close.
